I doubt it’ll be 40 episodes all at once. Like I said, it’ll probably be 10 episodes every 3 months.
Or they could give you all the finger and just do 10 episodes every 6 months like they’ll probably do for the second half of Dino Fury. Who knows.
I haven’t regularly watched Power Rangers since Super Megaforce, but as far as I’m aware, they’re still using the Super Sentai footage.
